3.0.1 and 3.1.1 Security AdvisorySeptember 18, 2007
Summary ======= Bugzilla is a Web-based bug-tracking system, used by a large number of software projects. This advisory covers a critical security issue that has recently been fixed in the Bugzilla code: * Even with account creation disabled, users can use the WebService to create an account. We strongly advise that 2.23.x and 3.0.x users upgrade to 3.0.2 immediately. Users of CVS HEAD or 3.1.1 should upgrade to 3.1.2 immediately. This is critical if you have a "requirelogin" installation and also have the WebService enabled. Vulnerability Details ===================== Class: Unauthorized Access Versions: 2.23.3 and above. Description: Bugzilla::WebService::User::offer_account_by_email does not check the "createemailregexp" parameter, and thus allows users to create accounts who would normally be denied account creation. The "emailregexp" parameter is still checked. If you do not have the SOAP::Lite Perl module installed on your Bugzilla system, your system is not vulnerable (because the Bugzilla WebService will not be enabled). Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=395632 Vulnerability Solutions ======================= The fix for the security bug mentioned in this advisory is included in the 3.0.2 and 3.1.2 releases. Upgrading to these releases will protect installations from possible exploits of this issue. Full release downloads, patches to upgrade Bugzilla from previous versions, and CVS upgrade instructions are available at: https://www.bugzilla.org/download/ If you are unable to upgrade, you should IMMEDIATELY apply the appropriate patch for your version: 2.23.x & 3.0.x: https://bugzilla.mozilla.org/attachment.cgi?id=280385 3.1.x: https://bugzilla.mozilla.org/attachment.cgi?id=280316 Credits ======= The Bugzilla team wish to thank the following people for their assistance in locating, advising us of, and assisting us to fix this issue: Sascha Jensen Frédéric Buclin Max Kanat-Alexander Marc Schumann General information about the Bugzilla bug-tracking system can be found at: https://www.bugzilla.org/ Comments and follow-ups can be directed to the mozilla.support.bugzilla newsgroup or the support-bugzilla mailing list. https://www.bugzilla.org/support/ has directions for accessing these forums.
